BSI publishes BS ISO/IEC 27090 guidance on AI-specific security threats such as prompt injection and data poisoning
BSI announced BS ISO/IEC 27090:2026, international guidance developed by ISO/IEC to help organizations identify and address security threats specific to AI systems. The guidance explains how attacks and vulnerabilities affect AI data, models, outputs and services across the AI life cycle, covering threats such as data poisoning, prompt injection, model theft and training-data leakage. It combines conventional cybersecurity controls with AI-specific measures and is designed to work alongside ISO/IEC 27001, 27002 and 42001.

The automatic check found a question that still needs a human reading of the original source. The discovery rationale is not a verified finding.
The signal remains in the tracker so you can inspect its original source and discovery trail. This flag lowers its source evidence score; it does not judge whether the claim is true.

A READER'S EVIDENCE CHECKHow to read this signalSix questions about claims, sources, risks, and open checks
This is a signal-level guide until claim-level evidence is available. “Not recorded” means the evidence has not been assessed here; it does not mean a result is false. How we check AI news →
- 01Who is making each claim?
The claimant and whether each claim was measured or asserted are not recorded in this public brief.
- 02What was actually tested?
Not recorded per claim. Check the source for sample size, tasks, model and benchmark versions, and reproducibility.
- 03Where are the sources?
Original link: www.bsigroup.com. Brief basis: fetched source page. Primary page date and quote locations are not established in this panel.
- 04What could mislead?
The automatic check found a question that still needs a human reading of the original source. The discovery rationale is not a verified finding.
- 05What is at risk if wrong?
Not assessed per claim. Consider safety, privacy, cost, and adoption decisions before relying on the result.
- 06What would change the view?
No claim-specific check is recorded. An inspectable primary method or independent replication could change the assessment.
Key findings from the stored brief
- The guidance covers threats including data poisoning, prompt injection, model theft and leakage of training data or model inputs.
- It maps threats to affected assets and to life-cycle stages from design and training through deployment and operation.
- It combines conventional cybersecurity controls with AI-specific measures and complements ISO/IEC 27001, 27002, 42001 and ETSI EN 304 223.
- BSI's research reports 75% of organizations had an AI failure in the past year, with 30% of those saying it led to a security breach.
Source claims not independently checked; survey figures come from BSI's own research and the guidance text was not reviewed directly.

BSI's London release dated 27 October 2026 says it has published BS ISO/IEC 27090:2026 in the UK, ISO/IEC guidance on detecting and mitigating AI-specific threats such as data poisoning, prompt injection, model theft and data leakage. BSI's own survey of 1,287 leaders found 75% had an AI failure in the past year. Guidance, not a certification. Page shows date only.
Source claims not independently checked; survey figures come from BSI's own research and the guidance text was not reviewed directly.

Timeline & updates
- Signal dated by source or discovery feed
This timestamp places the signal in the radar. It may be the discovery post date rather than the primary page's first publication date.
- Shared brief stored
AINewsIQ prepared one abstract from fetched source page.
A publication revision history is not stored for this signal. New engagement snapshots do not mean the source itself changed.
Why this may matter
AI systems introduce security risks that conventional cybersecurity measures were not designed to address. Structured guidance gives security, engineering, risk, governance and procurement teams a shared way to assess threats and choose proportionate safeguards.
Limits and open questions
Source claims not independently checked; survey figures come from BSI's own research and the guidance text was not reviewed directly.
Organization-specific financial, security, and operational effects require the organization's own context and review.
